goblins are wornderful
im just playing with them , and never lost battle
to use a starcraft language, goblin are used to zerg the enemy
at pair score, u have about 50% more units then enemy

i saw a lot of ppl bring close to me an army with swordmen and arciers, but just give formation to goblins (melee and archer), and use their run ability, so they jump on enemy like a swarm of locusts, and i win without give enemy time to understand lol
